SPECIFICATION forming part of Letters Patent No. 506,241, dated October10, 1893.

Application filed January 16, 1893. Serial No. 458.478- (No model.)

To all whom it may concern.-

Be it known that I, HIRAM D. LAYMAN, a citizen of the United States,residing at Little Rock, in the county of Pulaski and State of Arkansas,have invented a new and useful Automatic Railway-Pump, of which thefollowing is a specification.

My invention relates to improvements in that class of devices known astank-feeders or railway-pumps, the objects in view belng to provide acheaply constructed simple mechanism adapted to be employed inconnection with tanks and to be operated by the passing trains so as topump water from wells or other sources of supply into said tanks to beconveniently drawn off when desired.

Although I have herein shown and described the invention, as willhereinafter appear, 1n connection with railway-tanks, it will be obviousthat the said mechanism may be employed for various purposes, such forinstance, as pumping water out of mines, &c. I therefore do not limit myinvention to the specific use described; but hold that I may apply thesame to any of the various uses that may suggest themselves. With theseand other objects in view, the lnvention consists in certain features ofconstruction hereinafter specified and particularly pointed out in theclaims.

Referring to the drawings:-Figure 1 is a perspective view of a tank, andmechanism constructed in accordance with my invention connectedtherewith, the same being located at one side of a track. Fig. 2 is avertical section of a well, the pump to be operated by the mechanism andthe mechanism located over the pump. Fig. 3 is a transversevertical-section of said mechanism. Fig. 4 is a side elevation of aportion of a tender, the same being provided with a lever for engagingwith and operating the feed-mechanism. Fig. 5 is a transverse sectionthrough the way for carrying the cable. Fig. 6 is a plan of one of theguide-troughs and a portion of a tender.

Like numerals of reference indicate like parts in all the figures of thedrawings.

Upon a suitable tower or frame 1, constructed in any desired manner, issupported the tank 2; the same being thus elevated; and the tank is ofthe ordinary construction,

and hence needs no detail description. Below the tank, or to one side ofthe same, there is, in this instance, located a well 3, and upon the topof the same is supported a rectangular bed-frame 4. The bed-fran1e4 isprovided with bearings transversely opposite each other, and in thecentral pair is located a main transverse shaft 5, which shaft carries aspur-gear 6, and also a grooved drum-wheel 7, said gear and drum-wheelbeing made fast to and adapted to revolve with the shaft. In theend-bearings of the said bed-frame 4 are located transverse shafts 8,the ends of which terminate in crank-arms 9, and between said bearingsupon the shafts 8 there is mounted small spur-gears 10, two of whichengage with the spur-gear 6 at opposite sides thereof.

In a suitable frame 11 located below the bed-frame 4 and within the wellthere is jour-- naled a transverse shaft 12, and said shaft carries agrooved take-up wheel or pulley 13, which is located below thegrooved-wheel or pulley 7. The wheel 7 preferably has a series of threegrooves, while the take-up wheelhas a series of two grooves, all for apurpose hereinafter explained; though the number of grooves may bevaried as desired. Below the frame 11 is situated the pump-frame, whichconsists of opposite pairs of cross-timbers 14, and to these timbers aresecured a series of four pump cylinders 15, whose discharge branches orpipes 16, are provided with upwardly-opening valves 17, and communicatewith a receiving-chamber 18. Above the receiving-chamber 18 is locatedthe dischargechamber 19, and from it leads the dischargepipe 20, thatcommunicates with the aforesaid tank 2. Within the pump cylinders 15,valved piston-heads 21, are located and adapted to reciprocate, the samebeing connected with suitable operating-rods 22, whose lower ends arepivotally connected with the crank-pins of the crank-arms 9 located uponthe shafts 8. Communicating with the upper end of each cylinder abovethe piston-head 21 is a supply-pipe 23 the same being provided with aninwardly-opening valve 24, whereby it will beobserved each pump is alift-pump.

At the sides of the track and between it and the mechanism thusdescribed there is located a breast-frame which is constructed asfollows: Pairs of standards 25, rise from the ground and support across-head 26, said standards and cross-head being braced byoppositely-inclined braces 27. The cross-head has an opening 28 formedtherein, and in said opening is journaled a pair of grooved guidepulleys29 having an intermediate space. It will be understood that the framethus described may be altered in its construction, the only essentialitybeing that it is so constructed as to support the guide-pulleys.

30 designates acable, the ends of which are provided with metal loops oreyes 31, and between the ends and the loops the said cable is passedabout the pulley 7, thence downward in the reverse direction around thepulley 13, again over the pulley 7, and again over the pulley 13, andthence around the pulley 7, its two terminals passing out between theguide-rollers 28. It will be seen that when one terminal or loop 31 issupported between the guide-rollers in position for engagement by theengine the other terminal will be unwound from the pulley and extendsome considerable distance down the track. In order to provide asuitable support for the cable thus extended there is located at eachside of the pulleys a long trough or guide-way 32, the same having ageneral triangular-shape in cross-section and consisting of the backwall33, bottom 34, and inclined top 35. The outer edge of the top overlapsthe corresponding edge of the bottom, wherebya shed is formed forpreventing water from gaining access to the interior of the trough andthe bottom of said trough preferably terminates short of the back-wallthereby forming an opening or slot 36, whereby any moisture that maygain access may readily drip, so that the trough is kept dry and thecable is preserved against impairment by the weather.

37 designates the front portion of a tender of ordinary construction,and 38 designates one of the sills at the sides thereof. Upon each sillof the tender there is located a plurality of keepers 39, and in thesekeepers there is jourualed a rock-shaft 40, one end of which is bent atan angle to form a stud 41. Between the ends of the rock-shafts thereprojects therefrom a rock-arm 42, and the same is braced at its outerside by an inclined-brace 43. To the outer or free end of this rock-armthere is pivoted as at 44 a latch 45. This latch is pivoted between itsends so that its inner end overlaps that of the rock-arm and thecorresponding edges of thelatch and rockarm are provided with a shallowgroove or recess 46.

This completes the invention, with the exception of the twoliberating-posts 47, that are located some distance down the track andare in the path of the latch 45, when the rockarms 42 are extendedlaterally. Inthis manner, as will be obvious, the latches will beoperated upon their pivots 44, or swung to the rear, and will thusliberate the eye or ring 31, of that end of the cable that may beengaged in the manner hereinafter described. The rock-arm 42 normallyhangs in a vertical position, but it will be seen that an operator, suchas a fireman, may with the eyeend of his shaker-bar engage the bent end41 of the rock-shaft and elevate or partially rotate the rock-shaft,whereby the rock-arm 42 1s elevated.

In practice as will be apparent, one of the metal loops 31 is alwayslocated between and held supported in a horizontal position from theguidepulleys 29 and a passing train having its rock-arm above describedswung outward therefrom will engage the eye or loop 31 and thus carrythe cable, with the cable running in the trough, as before explained,and the rock-arm 42 that engages the cable extending into the slot inthe front of the trough. As the cable is drawn out it w ll be obviousthat the mechanism described Will. be set in motion the pumps beingoperated and serving to collectively force water into.

the receiving chamber 18, thence upward through the valved opening intothe d scharge-chamber 19 and out through the discharge-pipe 20 into thetank. As one terminal of the cable is thus unwound or earned in thedirection of the moving train, it will be obvious that the reverseaction is taking place upon the remaining terminal of said cable, inthat it is being drawn inward or toward the guide-pulleys. At the timethat the latch 45 is operated to liberate the unwinding terminal theloop at the opposite end of the cable will have been brought to theposition shown in Fig. 1, that is ready to engage any train going fromeither direction, so a repetition of the operation takes place. In thismanner it will be seen that the passing trains are utilized to keep thepump-mecham ism operating, and thus fill the tank so that it is alwaysready for use.

The tank is provided with the usual overflow-pipe so as to carry ofi anysurplus of water should the mechanism be operated too frequently for theconsumption of the Water, so that in this manner a complete supply isalways at hand.
